A favorite collection in Moving Images is A/V Geeks, which collects "ephemeral films" - those created for educational, industrial, or promotional purposes. As a former (okay, current) A/V Geek myself, I remember feeding movies like VD is for Everybody through the projector. Well, maybe not that particular movie...but still. See also: Beginning Responsibility: Lunchroom Manners (note the "Mr. Bungle" character - possibly the origin of the band name?).

Tomorrow we continue the series with an in-depth look at one of the collections in the Internet Archive's Moving Images Archive.

Also on Mental Floss:

DID YOU KNOW? Marlon Brando hated memorizing lines so much that he posted cue cards everywhere to help him get through scenes.
He even asked for lines to be written on an actress's posterior. (That request was denied.)
